Cadillac has already confirmed that there will be a new CTS coupe variant in 2015 as 2016 model, The ATS Coupe however will essentially be a 2-Door ATS for the most part bowing at the LA Auto Show in November.

From other spy shots I've seen it's going to be a more simple coupe version of the sedan. They are crazy not to make a CTS Coupe....I guess they are handing the market to the 6 Series, E Class Coupe, and A5. I guess they would rather not go with OR beyond the market. Too bad. I can tell you right now that there will be more i3's on he road than ELRs.

An ATS wagon would make the most sense, considering their intended targets (Audi A4, Mercedes C, BMW 3) all have one. As far as a replacement for the CTS coupe, why not just update the existing one? Sizewise, it already slots between the ATS and CTS (like the Audi A5 and Mercedes E coupe do) instead of being a direct 2-door version of either, if only to distance it from the smaller ELR.
